发明名称 Magnetic Tunnel Junction With Reduced Damage
摘要 A method includes patterning a metal layer to form a plurality of bottom electrode features, forming a Magnetic Tunnel Junction (MTJ) stack by a line-of-sight deposition process such that a first portion of the MTJ stack is formed on the bottom electrode features, and a second portion of the MTJ stack is formed on a level that is different than a top surface of the bottom electrode features, and performing a removal process to remove the second portion of the MTJ stack while leaving the first portion of the MTJ stack substantially intact.
